Background

A container spreader is a spreader that is used exclusively for loading and unloading containers.

A container spreader, refer to fig. 1 and 2, it includes the beam frame 1, the four corners of the beam frame 1 are all fixed with the lock steel bushing 11, and the lower end wall of the lock steel bushing 11 extends to the beam frame 1 below downward; the twist lock steel sleeve 11 is cuboid, and the length direction of the twist lock steel sleeve 11 is arranged along the length direction of the beam frame 1; the upper surface of the beam frame 1, which is positioned close to each spin lock steel bushing 11, is provided with a sliding hole 12 downwards in a penetrating way; in the width direction of the spin lock steel sleeve 11, each sliding hole 12 is positioned at one side of the corresponding spin lock steel sleeve 11 close to the center of the beam frame 1; the sliding hole 12 is a circular hole, the inner side wall of the sliding hole 12 is connected with the box rod 2 in a sliding mode, and the lower end wall of the box rod 2 is located between the lower surface of the beam frame 1 and the lower end wall of the spin lock steel sleeve 11; in the longitudinal direction of the twist lock steel bush 11, the end wall of one end of the twist lock steel bush 11 near the center of the beam frame 1 is an abutment surface 111, the closest point of the slide hole 12 from the center of the beam frame 1 is an abutment limit point 121, and the abutment limit point 121 is located on the side of the abutment surface 111 near the center of the beam frame 1.

Referring to fig. 2, the upper end wall of the twist lock steel sleeve 11 is provided with a rotation hole 112 penetrating downwards, a lock rod 113 penetrates through the rotation hole 112, and the lock rod 113 can rotate around its own axis; a lock head 1131 is fixedly welded on the lower end wall of the lock rod 113; a cam 1132 is fixedly arranged at the upper end of the lock rod 113, the cam 1132 is connected with a driving oil cylinder 1133, and the driving oil cylinder 1133 can drive the cam 1132 to rotate, so that the lock rod 113 is driven to rotate; a photoelectric sensor 13 is fixedly arranged at each position of the box rod 2 of the beam frame 1, and the sensing end of the photoelectric sensor 13 is positioned at one side right above the box rod 2 so as to sense the position of the box rod 2; the photoelectric sensors 13 are electrically connected with a PLC controller, which is electrically connected with signal lamps corresponding to each of the photoelectric sensors 13 one to one. When the lifting appliance is used, an operator lifts the lifting appliance through a crane and then moves the lifting appliance to be right above the container; at this time, the operator moves the spreader slowly until all the twist lock steel sleeves 11 are aligned with all the lifting holes of the container; next, the operator places the spreader down; when each twist lock steel sleeve 11 is inserted into a corresponding lifting hole, the lower end wall of the box rod 2 is abutted against the upper surface of the container, the box rod 2 moves upwards, meanwhile, the photoelectric sensor 13 detects the position of the box rod 2, and the PLC controller controls all signal lamps to be turned on; at this time, the operator starts the driving cylinder 1133 to drive the locking bar 113 to rotate, so as to drive the locking head 1131 to rotate by 90 degrees, and the upper end wall of the locking head 1131 abuts against the inner top wall of the container at the position where the hanging hole is arranged, so that the container can be lifted. In order to facilitate the insertion of the rotational lock steel sleeve 11 into the corresponding lifting hole, the length of the lifting hole is greater than that of the rotational lock steel sleeve 11, the width of the lifting hole is greater than that of the rotational lock steel sleeve 11, and the width of the lifting hole is less than that of the lock 1131.
